To aZZ w/wm it may concern.

Be it known that I, RUsH ALEXANDER, a citizen of the United States of America, rcsiding at 240 St. Louis street, Baton Rouge, in the parish of East Baton Rouge and State of Louisiana, have invented certain new and useful Improvements in Collapsible Paper Boxes, of which the following is a specification.

This invention relates to paper receptacles and more particularly to collapsible paper boxes and it has for its object to provide an article of this nature constructed in such manner that it may be shipped in collapsed form, may be set up in an instant and when set up will present an article of unusual strength and rigidity.

It is particularly an object of the invention to provide a paper box of the character indicated having its corners so constructed that they will be reinforced and braced so that they can not easily be torn and so that the box can not easily be crushed.

Further objects and advantages of the in vention will be set forth in the detailed description which now follows.

In the accompanying drawing Figure 1 is a plan view showing one corner of a box constructed in accordance with the invention, in plan and in collapsed condition;

Fig. 2 is a perspective view showing the parts in the position they occupy when the box is set up;

Fig. 3 is a perspective view looking from. the outside of the corner;

Fig. 4 is a view similar to Fig. 1 but showing a slightly modified form of the invention; and

Fig. 5 is a perspective view of the box illustrated in Fig. i but showing the same in assembled or set up position.

Like numerals designate corresponding parts throughout the several figures of the drawing.

Referring to the drawing and particularly to Figs. 1, 2 and 3, 5 designates the side, 6 the bottom and 7 the end of a box constructed in accordance with the invention. When the box is set up, see Fig. 2, a web 8 which constitutes an extension of the side 5 lies flat against the end 7, the upper edge of said web being received beneath a folded. over edge 10 formed partly upon the end 7 and partly upon a wing 11 which extends around the corner of the box and lies close to the side 5. Thus it will be seen that the protecting and reinforcing element provided by the folded over edge 10 not only engages the end 7 but also extends around and engages the upper edge of the side 5 adjacent the corner of the box. The side 5 is provided with an oblique slot 12 which receives the lower free corneiiof the wing 11 and further aids in tying the parts together and bracing the same.

When the parts are collapsed they lie in the position illustrated in Fig. 1 at which time the web 8 is folded upon the score line 13 while the wing 11 fits within the cut out portion is between the web 8 and the side 5.

A staple or like fastening element 15 passes through the folded over edge 10 and through the web 8 and through the end wall of the box and ties all of these parts together.

lVhen the box is to be brought to the position illustrated in Fig. 2 the wing 11 is first folded outwardly and side 5 and end 7 are brought to positions approximating the vertical; swingin upwardly on the score lines 5 and 7. uring this movement to the vertical the folded over edge 10 is sprung over the upper edge of the web 8, wing 11 is folded around the end and against the side 5 and the folded over edge 10 is caused to engage the upper edge of the side 5 after which the lower corner of the wing 11 is inserted in the slot.

In Figs. 4 and 5, designates the bottom of the box, 21 the side thereof, 22 the end thereof, 23 a web carried by the side and secured by a staple 24 to the end 22. This staple likewise passes through a folded over edge 25 formed partly upon the end 22 and partly upon a wing 26 which extends around. the corner of the box and lies flat against the side 21. The operation of erecting this form of the box is the same as that described with respect to Figs. 1, 2 and 3 except that the slot 12 is omitted and the web 23 is not out out for the reception of the wing 26 as at 14 in Fig. 2, but upon the contrary this web extends from the lower inside corner of the box upwardly and constitutes a brace throughout the entire height of the corner of the box.

It will thus be seen that the corner of the box is eflectuaflly braced and reinforced in every direction. The wings 11 and 26 brace the outer side'of the ends of the sides. webs S and 23 brace the ends from the sides and vice versa, While the turned over edges 10 and 25 not only form a lock for positively holding the box in assembled position, but brace the parts, lend additional rigidity to the same and prevent tearing vor crushing of the box at the corners. 7

It is to be understood that theinvention is not limited to the precise construction set forth 'but tha-t it includes Within its purview Whatever changes fairly come within either both the said end and wing and adapted to engage over the upper edge of the side and the upper edge otthe Web.

2. A box of the character described comprising a bottom, side and end, a Web can ried by the side and extending across the end, a Wing carried by the end and extendalong the outside of the side, an integral turned over edge extendingcontinuously along both the said end and wing, a fastening element traversing said overturned edge at substantially the center of said end and passing through the web and the end of the box, said Web being obllquel v scored as and for the purposes set forth.

In testimony whereof I aflix my signature in thepresence'o'f two Witnesses.
